Weather in Bandung in May

Shoulder season. May is shoulder season in Bandung — cheaper, quieter, and a genuine gamble. You should expect rain on 22 days of the month, which is more days wet than dry.

May ranks 8 of 12 in Bandung: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 22 of the month's 31 days, 6 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 90% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average May reaches 30 °C. Across the twenty years measured, the hottest May day reached 29.4 °C and the coldest night fell to 16 °C, and the wettest single day dropped 50 mm — roughly 28% of the month's rain in one day.

May is moderately variable: 72 mm in the driest year against 498 mm in the wettest, around an average of 177 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 4.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 90% is the real story though — it is the number that decides how the day feels, not the 27.1 °C.

How May sits in the year

Temperatures hold steady either side: 26.9 °C in April, 27.1 here, 26.6 in June. Nothing about the timing within the month matters much. Rain is the thing that moves: June brings 7 days less of it, so pushing the dates later buys drier weather.

Daylight in May

Bandung sits close enough to the equator that daylight barely moves all year — 11.8 hours in May, against a range of just 0.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 10.8 °C between the year's warmest afternoons and coldest nights. At 714 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

May in Bandung versus nearby

If Bandung is one option among several, the nearby comparison is worth making. Jakarta is close enough to be a coin toss — 2.6 °C warmer, 3 days more rain. Bandar Lampung is close enough to be a coin toss — 2.2 °C warmer, 4 days less rain.

So: May is a compromise. August is 23 points better and is what Bandung is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
